Michael Bennet's holding on to a small lead the day before the Democratic primary for US Senate in Colorado, 49-43 over challenger Andrew Romanoff.
Snip
Both candidates are relatively popular with Bennet holding a 57/24 approval rating and Romanoff sporting a 52/27 favorability spread. Bennet's approval rating with primary voters was 53/22 when PPP last looked at the race in May so the spirited primary campaign doesn't appear to have had a negative impact on his overall popularity within the party, a good sign for him if he does indeed move onto the fall.
